sinuated anteriorly and sparingly toothed, posteriorly rectangular, 

 somewhat reflexed and slightly pointed at the lateral angles, posterior 

 margin feebly rounded, with a few tubercles on the outer sides; the 

 anterior margin narrowly rimmed, not broader than the neck; the cal- 

 losities not prominent, bordered by a narrow, sunken line; surface of 

 thorax feebly rounded at the disk, very rugose, roughly irregular punc- 

 tured and with numerous deep sunken pits, the larger ones grouped 

 more on the sides and in front of thorax; at the submarginal part of 

 the posterior margin a transverse faint ridge and at each end of it a 

 short impression. Scutellum triangular, as long as broad, unevenly 

 wrinkled. 



Hemilytra dense and confluently punctured, not roughly as on the 

 thorax, no trace of a transverse light band or any zig-zag line; costal 

 margins nearly straight; membrane dark bronze. Dorsal part of 

 abdomen blackish, with a yellowish stripe down the middle. Wings 

 smoky. Connexivum dark brown, a short, transverse, pale band at 

 each incision. The underside of the body densely covered with short 

 golden hairs and numerous black dots; a median, longitudinal impres- 

 sion extends down the venter to the fourth or fifth abdominal segment. 

 Front and middle femora light brown, spined beneath; the tibia and 

 tarsal joints yellowish; hind femora thickened towards apex in both 

 sexes, dark reddish brown, paler at the base and covered with small black 

 tubercles; the underside carries two rows of strongly curved, blackish 

 spines. The hind tibiae moderately expanded from near the base to 

 about one-third of its length, dark brown, with a small transparent 

 spot on the inner margin; the expansion rounded, narrowing to either 

 end; the outer margin feebly sinuated twice, having two or three small 

 acute spines; the inner margin a little less broadened than the outer 

 margin, with a few short spines at the edge and some minute ones at 

 the inner side of the simple apical part of tibiae, which is, with the 

 tarsal joints, yellowish-brown and very hairy. 



Length 18 to 21 mm. ; width across thorax 6 to 8 mm. 



Described from two specimens, male and female, collected 

 on a magnolia tree in the city of Washington, District of 

 Columbia, September 20, 1889, September 19, 1905 (Heide- 

 mann). In addition several other specimens have been ex- 

 amined, from Georgia, State College (Scott and Fisk); Florida 

 (Ashmead); Chapel Hill, North Carolina, October 1, 1881 (G. 

 F. Atkinson). 



Type: No. 13228, U. S. National Museum. 



This species is very distinct from any other species known, 

 by the peculiar rough surface of the thorax. It is related to 

 L. stigma Herbst, but differs in having the hind tibiae less 

 expanded and showing no indication whatever of a pale band
